Do Car Seats Really Expire?
Yes. Car seats have a manufacturer-set expiration date -- typically 6-10 years from the date of manufacture, ranging 4-12 years depending on the brand. There is no single federal expiration mandate; each manufacturer decides and labels its own date.
The one thing to know: Car seats expire because the plastic shell, foam, and metal hardware degrade with age, heat, and UV exposure even without a crash — and because testing standards keep improving. There is no single federal expiration rule; each manufacturer sets and labels its own date, typically 6-10 years from manufacture.
Why manufacturers set an expiration at all
Plastic shells, energy-absorbing foam, webbing, and metal hardware can degrade with age, heat, cold, and UV exposure, even without a crash. Crash-test standards and design also keep improving, so an older seat's protection level may lag behind a current one even if it still looks intact.
How to check your specific seat
Look for a label -- often on the underside, back, or a sticker near the manufacture date -- stating either an explicit expiration date or a number of years from manufacture. When in doubt, contact the manufacturer directly with the model number.

Frequently Asked Questions
Yes. Manufacturers set an expiration date -- typically 6-10 years from the date of manufacture, though it ranges 4-12 years by brand -- based on material degradation and evolving crash-test standards.
No single federal expiration mandate exists. It is each manufacturer's own decision, based on their materials and updated safety-standard testing, and the date is printed or molded on the seat.
Check the label on the seat itself (often on the underside or back) and the printed manual -- it's usually stated as a date or as years from the manufacture date.
The plastic shell, energy-absorbing foam, webbing, and metal hardware can all weaken with age, heat, cold, and UV exposure, even if the seat looks fine and has never been in a crash.
